Water Systems

Committed to innovative water system solutions for storage, heating, expansion and flow control along with a host of related HVAC products serving the residential, commercial and industrial markets.

AMTROL® revolutionized the hydronic industry in 1954 with the introduction of EXTROL®, the world’s first pre-pressurized diaphragm expansion tank. Smaller, lighter and more reliable than traditional air-over-water tanks, EXTROL remains the gold standard. This innovation was followed in 1963 with the launch of WELL-X-TROL®, the first pre-pressurized well tank. In 1980, AMTROL invented the BOILERMATE® indirect-fired water heater which used re-circulated boiler water to heat a home’s potable water, saving money and energy. THERM-X-TROL® was AMTROL’s next big breakthrough in 1991. This innovation was so important that thermal expansion tanks are now code-required on all water heaters.

Today, AMTROL remains committed to innovative water system solutions for storage, heating, expansion and flow control along with a host of related HVAC products serving the residential, commercial and industrial markets. Visit amtrol.com for more information on our products.
